You or your hosting provider needs to examine the outgoing MTA logs to
see the status of delivery of messages from the list to these users. If
they are not being accepted by the user's ISPs, you need to understand
why. This FAQ <https://wiki.list.org/x/4030690> may help.

If it is a DMARC issue, this <https://wiki.list.org/DEV/DMARC> may help

Only indirectly. Bounce processing will eventually disable delivery to
and unsubscribe bouncing users, but it won't create delivery issues.
